Hi ,
I found a bug that may be related to da_llxy.inc program and I need your help!

Using different numbers of computational cores on the same node can lead to differences in the amount of observations assimilated.

Fig1 Only 1 computing core used

Fig2 Use of 4 cores
The number of observations in the “Local” column varies in Fig1 and Fig2.
The information in the compiler is as follows:
~/mpi/intelmpi/2017.4.239/intel64/bin/mpicc
